Aerosol composition comprising silicate particles and surfactants

ABSTRACT

The invention concerns a cosmetic composition, in particular for the hair, packaged in an aerosol device containing a propellant and a liquid phase which comprises, in a cosmetically acceptable medium: (i) solid particles containing at least 10 wt. % of at least a silicate, and (ii) at least a surfactant; said solid particles containing less than 1 wt. % of aluminium.

The present invention relates to a composition packaged in an aerosol device comprising a propellant and a liquid phase, which contains, in a cosmetically acceptable medium, silicate particles, to a cosmetic process for treating the hair and to a use as a styling product.

Styling products are usually used to construct and structure the hairstyle and give it long-lasting hold. To do this, film-forming polymers are introduced into a cosmetically acceptable medium. However, certain polymers result in hardening of the hair and/or a sticky nature. As a result, the hair is often stuck together, and the hair shape is destroyed upon disentangling.

To overcome these drawbacks, it has already been proposed to use solid powder in cosmetic compositions, such as metal oxide powders. For example, patent U.S. Pat. No. 3,819,827 describes hairsetting products comprising from 0.2% to 6% by weight of aluminum oxide particles with a particle size of about 30 μm.

Similarly, patent application EP 1 005 849 describes the use of fine solid mineral powders, for instance calcium carbonate, aluminum hydroxide, magnesium carbonate, calcium phosphate, calcium oxalate or barium sulfate powders, in cosmetic hair compositions containing at least two liquid phases. It is pointed out that such compositions give the hair especially advantageous effects when the composition is packaged, without a propellant, in a device capable of spraying the composition onto the hair.

Patent DE 25 42 338 describes propellant-free lotions and sprays for fixing the hair, comprising silicate particles, in an alcoholic or aqueous-alcoholic medium, the silicate concentration being between 0.1% and 4%.

The Applicant has found, surprisingly and unexpectedly, that by selecting silicate particles as solid particles, it is possible to obtain good cosmetic properties and to obtain styling without making the hair sticky or overloading it, insofar as the composition is packaged in a particular device, namely an aerosol device, when the cosmetic composition also comprises at least one surfactant.

One subject of the invention is a cosmetic composition, especially a hair composition, packaged in an aerosol device containing a propellant and a liquid phase, which comprises, in a cosmetically acceptable medium:

-   -   (i) solid particles containing at least 10% by weight of at         least one silicate, and     -   (ii) at least one surfactant, said solid particles containing         less than 1% aluminum.

Another subject of the present invention consists of a cosmetic hair treatment process using the composition according to the invention.

Another subject of the invention is the use of the cosmetic hair composition, especially for fixing and/or holding the hair in a desired shape.

The invention is also directed toward the use, in hair cosmetics, especially for fixing and/or holding the hair in a desired shape, of a cosmetic composition packaged in an aerosol device containing a propellant and a liquid phase, which comprises, in a cosmetically acceptable medium, solid particles containing at least 10% by weight of at least one silicate, said solid particles containing less than 1% by weight of aluminum.

Preferably, the solid particles contain between 0 and 1% aluminum and more preferably between 0 and 0.5% aluminum.

Other subjects, characteristics, aspects and advantages of the invention will emerge even more clearly on reading the description and the various examples that follow.

Particles

Advantageously, the solid particles have a number-average primary size of between 2 nm and 1 μm.

The particles containing at least 10% by weight of at least one silicate preferably have a number-average primary size of between 5 and 500 nm and more preferably between 10 and 250 nm.

The particles according to the invention may be in any form, for example in the form of spheres, flakes, needles, platelets or totally random forms.

The particles are preferably sodium, magnesium and/or lithium silicates, for instance the compounds sold by the company Laporte under the names Laponite XLG and Laponite XLS.

For the purposes of the present invention, the expression “primary particle size” means the maximum size that it is possible to measure between two diametrically opposite points on an individual particle. The size may be determined, for example, by transmission electron microscopy or by measuring the specific surface area by the BET method, or alternatively using a laser granulometer.

When the particles are formed from silicate and other fillers, the silicate is in free form and does not form chemical bonds with the other fillers. This is then a case of an alloy between the silicate and other fillers, especially with metal or metalloid oxides, in particular obtained by thermal fusion of these various constituents.

When the particles containing at least 10% by weight of at least one silicate also comprise a metal or metalloid oxide, this oxide is chosen especially from silicon oxide, boron oxide and aluminum oxide.

Preferably, the particles contain at least 50% by weight of silicate and better still at least 70% by weight of silicate, and particles consisting of more than 90% by weight of silicate are particularly preferred according to the present invention.

The silicate that is suitable for use in the compositions of the present invention may be of natural origin or may be of synthetic origin.

The silicate-containing particles according to the invention are especially used in an amount of between 0.01% and 10% by weight and preferably between 0.5% and 3% by weight relative to the total weight of the composition.

The composition according to the invention may also contain other types of particle, for example titanium oxide, zinc oxide or aluminum oxide particles.
